SNOW-REMOVING DEVICE.

Application filed April 2,

[ all 1.0710772, it may concern:

Be it know-vii that I, MARCO BELTRAMI, a citizen of the United States,residing at Framingham, in the *ounty of Middlesex and State ofllassachusetts, have invented new and useful Improvements inSnow-Removing Devices, of which the following is a specification.

This invention relates to snow plows adapted to be positioned in frontof a locomotive for the purpose of removing the snow from the tracks anddepositing it upon one side thereof.

Another object of the invention is the provision of a snow plow of thischaracter in which steam from the locomotive is utilized for. thepurpose of softening and break ing up the snow and ice, to facilitateits removal from the track.

Other objects and advantages of the invention will appear as thefollowing description is read in connection with the accompanyingdrawings.

In the drawings:

Figure 1 is a side elevation of a portion of a locomotive showing theapplication of the invention.

Figure 2 is a top plan view of the same.

Figure 3 is a view similar to Figure 1 with the plow shown in section.

Figure 4; is a front elevation.

Figure 5 is a fragmentary section taken longitudinally of the conveyor.

Figure 6 is a fragmentary plan view of the conveyor.

Figure 7 is a fragmentary plan view of the forward portion of the plowshowing the steam nozzle and its protecting shoe in horizontal section.

Referring in detail to the drawings, wherein like characters ofreference denote corresponding parts, the reference character 10indicates a portion of a locomotive to which the plow 11 is shown asattached.

This plow includes a body 12 which comprises spaced parallel members orbeams 13, which are suitably connected together and through whichextends a forwardly projecting arm 1a which is designed to support a 1air of forwardly extending wings 15.

hese wings are connected together at their forward ends as at 16 and arecurved rearwardly and outwardly so as to provide an upwardly andrearwardly extending trough. 17.

tending transversely of the plow in front of the locomotive 1s anendless conveyor 18. This conveyor 1s formed of a plurality of plates orbars 19 which are connected at W each end to chains 20, the latterpassing over sprockets 21. The sprockets 21 are mounted upon shafts 22,which also have secured thereon sprockets 23, the latter being connectedby means of chains 24 to sprockets 25, which are mounted upon a centralshaft 26, so that an operation of this last mentioned shaft will operatethe conveyor. The conveyor is divided into trough-like compartmentsthrough the medium of blades 27, the latter being pivot-ally mounted asshown at 28 and provided with inwardly extending arms 29, which bearupon and travel over a member 30 arranged within the conveyor andmounted upon the shafts 22. Bv

this means the blades 27 are held in vertical oosition during the travelalong the upper flight of the conveyor, the arms 29 being so disposed asto resist pivotal movement in a direction opposite to the direction oftravel.

The plow is connected to the locomotive through the medium of a couplingmember 31, which is adapted for connection to a couplin member 32usually provided at the power, such as electricity or through the mediumof steam supplied from the boiler. The shaft of this motor is connectedto the shaft 26 through a slip joint 34, while at each end of the slipjoint there is provided a universal joint 35, so that relative movementof the locomotive and plow will be compensated for.

In the operation of the plow, the snow upon the track will be forcedupward along the troughs 17 and deposited upon the conveyor within thetrough-like compartments provided between the blades 27, whereupon theconveyor will move the snow to one side of the plow and direct itthrough a chute 36 to one side of the track. the mountmg of the bladespermitting the latter to readily pass downward between the end of theconveyor and the adjacent end of the chute.

For the purpose of more readily breaking up the snow and ice in theevent of the same being tightly packed, the invention provides means forsupplying steam to the front end of the plow'to act upon the snow andice. To accomplish this there is provided a nozzle 37 which is disposedvertically in front ofthe wings 15 and is provided with spaced openings38 for directing jets of steam upon opposite sides of the point 16 ofthe wings. This nozzle is located at one end of a steam pipe 39 whichhas a flexible connection 40 with a pipe e1, This last mentioned pipe.is connected to the steam supply at any desired point, for. example, the

steam'dome 42 of the locomotive and is provided with a valve 43 by meansofwhich the supply of steam may be regulated. At the forward extremityof the plow there is pro vided a shoe M which encloses the nozzle 37 :soasto protect the latter.

extending arm terminating in a wedgeshaped portion, a pair vofwing-plates secured to opposite sides of the wedge-shaped portions, theforward ends of said plates converging together'to form a point and the.rear ends of the plates belng curved to provide upwardly inclinedtroughs and a conveyor positioned ad acent, the rear. ends of thetroughs to receive the snow discharged therefrom. r

2. snow plow comprising a plow member presenting vertically disposedcutting edge; a vertically disposed nozzle mounted directly in front ofand parallel tosaid cutting edge; said nozzle being formed With avertical series of openings, and means for supplying steam thereto.

3. A device as recited in claim 2 including a protecting shoe fittingover the said nozzle.

t. A device as recitedin claim 3 including" a protecting shoe fittingover said nozzle and provided with a forwardly directed cutting edge.

5. IILIZOIIllJlllatlOII, a locomotive, a trans versely extending wheeledframe positioned in front of the locomotive and coupled thereto, an armprojecting forwardly from the frame, a pa r of oppositely disposedwingplates carried bythe arm, the forward ends of'the plates convergingtogether to form a point and the rearwardly diverging ends I of theplates being shaped to afford upwardly inclining troughs,'a conveyormounted on the'frame adjacent the upper ends of the troughs, a motorcarried by the locomotive, and a drive connection between the motorv andthe conveyor including universal and slip joints arranged to permitnecessary relative movement of the. parts connected thereby.

In testimony whereof I afliX my signature.
